Description
These lightweight Danfoss Group 3 gear motors have an aluminium construction and pressure-balanced bearing blocks for maximum performance across the entire operating range.
Teflon-coated bushings extend life under extreme temperature, pressure and speed conditions. Meanwhile, one-piece gears minimise deflection under pressure.
The motor is highly efficient, has an excellent starting torque and is available in 10 frame/displacement sizes:
